 ## entry
 when using libk, your program's entry point will not be the `int main(int,char**)` function that libc opens into. libk will call the function `stat entry(kenv)` instead. like libc, the value returned by `entry` will be returned to the host platform.
 
 ## types
-kcore contains fixed-width integer types. note that the available of each depends on your platform; compilation will fail if e.g. you try to use a u64 or a u128 on a 32-bit platform, so where exact lengths are not required, you may wish to use the built-in C types instead.

 ### struct kenv
 `kenv` is a struct that encompasses the environment the program was launched in.
  * `kiochan std` - a stereo IO channel for reading and writing to and from stdout.
  * `kiochan err` - a mono IO channel for writing to stderr.
- * `kvar* env` - a pointer into the program's environment
+ * `kvar* vars` - a pointer into the program's environment
 
 ### struct kvar
 `kvar` is a struct that abstracts over platform environment variables.
  * `kstr name` - the name of an environment variable
  * `kstr val` - the value of an environment variable
  * `char* platform` - a pointer into the platform's underlying representation
